Protoform Bots hypothosis

I just got to thinking, if you remember from the first trailer, there were a few bots landing in Egypt, (this is a huge IF) but what if they were proptoforms of the brothers of the Fallen, like maybe some of the original 13......Long shot I know, but.....

the protoforms crashing in the desert are shown several times in the new trailer, they are identical to each other and have heads that are very similar to blackout's, with bodies more similar to protoform prime. there is one grabbing the camera, and two fighting next to each other in the desert and getting blown up, one has a large mini-gun which he drops when shot in the face. they are clearly on the decepticons' side, they are shooting hte humans, and walking through the ruins together with scrapper and starscream.
